Quick answer
A platform policy — required for DMCA safe harbor — under which accounts that accumulate multiple valid IP complaints are suspended or terminated.
Repeat-infringer enforcement is the rights holder's path from listing-level whack-a-mole to account-level resolution. Filing a documented report for every violation, and referencing prior complaints, is what triggers these policies on Etsy, Amazon, eBay, and social platforms.
